I really love the thumpy, not buzzy, vibrations of my Ina, but its shape and design - not so much. Can anyone who has experience with an Ina share if there is another vibrator with similar quality of vibrations? I'm only interested in multifunction vibes with different patterns as well as the strong-ish (but adjustable) thumpy type vibrations. Any shape/style is fine. Thanks for any input you can give!
